Code Domain Phase (Phase)
Code domain phase is the difference in phase between the pilot and
other code channels (Walsh codes) within the same forward CDMA
channel. It displays the phase error for each of the 64 Walsh channels
relative to the pilot channel (Walsh 0). This measurement is indicated
as positive or negative bars on the Test Set’s CODE DOM screen. The
size of the bar indicates how much the phase of other Walsh codes lead
or lag the pilot. Signals above the reference are leading in phase;
signals below the reference are lagging.
